To (zZZwhomtm-ay concern: the arrangement of the disks on the shaft Be it known that LSAMUEL K. DnNNIs, varied as desired, and for this purpose I a citizen of the United States, residing at provide a removable bearing-cap 13. The Chicago, in the county of Cook and State particular form of roller used and journal 5 of Illinois, have invented certain new and bearing employed do not form part of my useful Improvements in Land Packers, of present. invention and it should be underwhich the following is a full clear, and stood that any equivalent form of clod crushezract specification. ing tool or hearing may be substituted.

My invention relates to land rollers of The links 7 in which the roller shafts are 10 the type known as sub-soil packers or cultijournaled are preferably straight and each vating packers, and the object of the inlink is formed with the vertically extendvention is to improve the crushing and leveling longitudinal slot 8 which is bridged near ing action of machines of this character either end and at equal distances from the employing a succession of two or more parcenter of the link by bearing pins 9 which.

allel rollers or equivalent ground working are retained in placeby cotter pins or tools, and I accomplish this purpose by similar means these pins 9 being approxiconstructing such a machine with a novel mately in the same horizontal plane as the form of rocking joint between the upper axes of the roller shafts. Positioned above frame and the roller carrying frame conthe roller frame there is an upper or weight- 20 sisting of a pair of seats on the upper frame frame 10 to which the draft tongue is atspaced in a fore and aft direction and entached and which is preferably constructed gaging the roller frame at points equally of angle bars placed with one flange exspaced from its center so that the roller tending in a horizontal direction to permit frame when passing over uneven ground will a bottom closure to be placed thereon and 25 cause the weight of the upper frame to the frame used as a weight box if desired. be thrown first on the forward bearing and At either end, this frame is provided with then on the rear bearing as the front and depending brackets 11 which terminate in rear rollers pass over a rise in the soil. a pair of spaced seats 12 such as the slots /Vith this main and other incidental obshown in Figure 4, these seats resting on 30 jects in view my invention consists of the both pins 9 when the rollers are traveling on organization and details of construction or an even surface. With this construction it their equivalents, described in the followwill be evident that the point of connection in I specification and defined in the claims. between the frames is low down on the roller Referring to the drawingsframe and well within the plane in which 35 Fig. 1 is a plan view, with parts broken the rollers lie and that the lower Or roller so away, of a land roller embodying my invenframe can rock on the upper frame on either tion. pin 9 and it results, therefore, that as the Fig. 2 is an end View. forward roller passes over a rise or ob- Fig. 3 is a front view of one end of the struction, such as clods on the ground the to machine, and upper or weight frame will be raised on the Fig. l is a detail View of the lower end front bearing and the weight of the frame of one of the bearing brackets. thrown principally on the forward roller,

In the present instance 1 illustrate my the action being repeated and the frame invention as embodied in a packing and raised on the rear bearing when the rear cultivating roller employing a pair of parroller passes over the obstruction, with the roe allel front and rear rollers 5 and 6, these result that practically the whole weight of rollers being preferably of equal diameter the upper frame is twice applied to leveling and made up of separate disks of well the ground, greatly increasing the elliciency known form which are clamped together on of this type of machine. so shafts journaled in the ends of the links 7. While the construction here described ere ice.

These shafts are preferably journaled in emplifies one form which my invention may U the links so as to be readily removable from take, it is not to be regarded as limited the hearings or movable longitudinally therethereto and various modes of connecting the thru to enable one or more of the disks upper and lower frames so that the weight as comprising each roller to be removed and of the upper frame is shifted from, front to rear as described could be substituted within the scope of the following claims.

I claim as my invention:

1. In a cultivating implement, the combination of a frame including successive tool carrying shafts, a weight frame above said tool frame, and a connection between the frames permitting them to rock on each other in afore and aft direction on points of support located in a horizontal plane with the axes of the tool shafts and including means for causing the bearing point of the weight frame on the tool frame to shift in a fore and aft direction as the tool frame is rocked by travel over uneven ground.

2. In a cultivating implement, the combination of a frame including successive tool carrying shafts, a weight frame above said tool frame, and a connection between the frames permitting them to rock on eaclr, other in a fore and aft direction on two axes located in a horizontal plane with the axes of the tool shafts and including means causing the axis of pivotal movement to shift from one to the other of said axes as the tool frame is rocked by travel over uneven ground.

3. In a land roller, the combination of a frame comprising successive roller carrying shafts, a frame above said first frame and a rocking joint between the frames including aplur'ality of transverse bearings located at points Within the plane of the rollers and spaced from each other in a fore and aft direction.

4. In a land roller, the combination of a frame con'iprising successive roller carrying shafts, a frame above said first frame and a rocking joint between the frames including a; plurality of transverse pivotal connections spaced from each other in a fore and aft direction and engaging the first frame at points spaced equal. distances from the axes of said shafts.

'n a land roller, the combination of a frame comprising successive roller carrying shafts, a frame above said first frame, and a rocking joint. between the frames including a plurality of transverse bearings located at points within the plane of the roll-' ers and spaced from each other in a fore and aft direction, and engaging the first frame at points between the axes of said shafts.

6. In a land roller, the combination of successive roller carrying shafts, links connecting the ends of said shafts, a frame above said shafts and provided with end brackets having front and rear bearing slots and bearing pins on said links spacedequal distances from the middle thereof and received in said slots.

7. In a land roller, the combination of successive roller carrying shaft-s, links connecting the ends of said shafts, a frame above said shafts and provided with end brackets having front and rear bearing slots and bearing pins on said links received in said slots.

i 8. In a land roller, the combination of successive roller carrying shafts, links connecting the shafts, a frame above said shafts and provided with brackets having front and rear bearing slots and bearing pins on said links received in said slots.

9. In a land roller, the combination of successive parallel roller carrying shafts, links connecting the shafts, a frame above said shafts and provided with brackets each of which has a pair of seats loosely engaging one of said links.

'10. In a land roller, the combination of successive parallel roller carrying shafts, links connecting the shafts, a frame above said shafts and provided with brackets, each of which has a pair of seats loosely engagingone of said links intermediate their connections to the shafts.

11. A land roller comprising a pair of parallel roller carrying shafts, connecting links in which the shafts are journaled, said links being provided with vertically extending slots intermediate the shaft bearings, a pair of spaced bearing elements bridging each of said slots and a frame positioned above the rollers and provided with brackets having seats resting on said bearing elements.

12. A land roller comprising a pair of parallel roller carrying shafts, connecting links in which the ends of the shafts are journaled, a frame above the rollers extending from end to end thereof and having depending end brackets each formed with a pair of spaced seats engaging the links and permitting pivotal movement on either-seat.

In testimony whereof I affix my signa ture.
